yeah...the conversation doesn't make all too much sense to people who understand it fully

Some of us would have to be there to hear what is all said.
HDTVs only display...and they display better imagery if given the proper source, ie., HD content. They actually display SD imagery the same as standard tubes...but they do not have scanlines to create the perception of better SD images. Same concept applies if you every mess with old arcade emus...and they have blitters that enable a scanline effect...the image then is percieved to be "sharper".
Satellite internet has some limitations too, aside from the overcast drops (sometimes)....
